International Classification:

F16D 6904

US Classification:

192107M

Abstract:

A clutch and brake friction assembly for a heavy duty vehicle is provided which includes a metal shoe having an exterior backing surface. The surface is provided with a multitude of burr-like protuberances arranged in a predetermined pattern throughout the surface. Molded to the backing surface and mechanically interlocking with the burr-like protuberances thereof is a lamina of friction material.

Abstract:

A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating. The resulting product may be classified as a hybrid friction material, i. e.
